This invention'relates to a window opener and one object of theinvention is; to provide a device of this characten-by meansv of whicheither an upper or a lowersash may be, easily i 5 moved in an openingdirection. It often hap pens that a window sash will be purposely fittedvery tightly in its frame' or becomes swollen during damp weather andcannot be readily opened but by employing; a device 1 such asillustrated in the accompanying drawings either an upper or a "lowersash maybe easily moved in an opening directlon. Another ob ect of theinventionis to so or inarring the sash or adjacent portions of a windowframe.
